N2 - In this work, a new intercalated FeS compound: (C2H8N2)0.4Fe2S2 was synthesized via the solvothermal route. The product is stable in air and shows the micron-sized plate shape. Structure refinement indicates that (C2H8N2)0.4Fe2S2 adopts the I4/m space group with the lattice constants a = 3.6906(6) and c = 20.4215(11) Å. The [FeS] layer crystallizes into the anti-fluorite structure with edge-sharing tetrahedrons and the C2H8N2 molecules are inserted in between the layers. (C2H8N2)0.4Fe2S2 is the first intercalated FeS compound reported up to now that contains the electroneutral guest layers. This specific feature leads to the paramagnetic behavior without any magnetic transition in the measured temperature range. Furthermore, we find that the ferromagnetic interaction can also be easily induced in this compound by inserting the extra Fe in between the layers, indicating the controllable magnetism of the title compound. The absence of superconductivity in (C2H8N2)0.4Fe2S2 is mainly due to the external pressure on FeS layers induced by En intercalation.
